Abstract

Using the local Hall effect (LHE), we have succeeded in detecting a magnetic domain wall (DW) trapped in a permalloy Ni80Fe20 wire and in clearly distinguishing whether the DW structure is a head-to-head or a tail-to-tail DW. The LHE method has an advantage of large signal and makes it possible to investigate the inner DW structure.
